A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

How an ABS pump with control module works
The module electronics store fault codes that can be read with a diagnostic tool. This makes it easier to determine whether the sensors, the wiring or the hydraulic unit itself is to blame.
Matching
Compare number 96817739 in full with the number on your pump. Different versions were fitted to the same models, so the number decides the fit, not the model alone. The brake system is critical for safety, so fitting is best left to a workshop that will bleed the brakes and check ABS operation.
Symptoms of a faulty ABS pump
- ABS does not react to wheel slip,
- ESP or ASR does not switch on,
- power supply faults in the diagnostic memory,
- signs of corrosion are visible on the connector.
Inspect the control module connector: corrosion or burnt contacts cause symptoms similar to faulty electronics.
